' UNITED 'STATES PATENT OFFICE FRANK E. STAHL, OF TONAWANIDA, NEW YORK, ASSIG-NOR TO THE COLUMBUS MGKINNON CHAIN CORPORATION, OF TONAWANIDA, NEW YORK, A CORPORATION OF OHIO CROSS CHAIN FOR ANTISKID DEVICES Application filed April 30,

This invention relates to chains for antiskid devices for use onrwheels, and, more particularly to cross chains for such devices.

The object ofthe invention is to provide 6 an improved, simplified and inexpensive form of link for such chains whereby the chain is rendered more effective in biting into the road or the ice on the road to prevent skidding. This effectiveness of link is obtained without producing serious wear on the tire. Other objects will appear from the disclosure herein. 7

The invention is embodied in the example herein shown and described, the features of novelty being finally claimed.

In the accompanying drawing Figure 1 is an edge view of the link according to the invention. 7

Fig. 2 is a plan view of the same looking upward at Fig. 1.

Fig. 3'illustrates three of the links.

Fig. 4 is a cross section of the link on the line IVIV Fig. 1.

Fig. .5 illustrates across chain as the same appears applied to a tire casing, the latter being a cross section.

In the views like characters of reference designate corresponding parts.

The l nk is manufactured from wire formedln a die of the cross section shown I in Fig. 4, that is to say of'ovate form with.

the one side at 8 round the other tapered to I into a previously formed link in makingthe chain. The straight link when formed is oppositely twisted at its bent ends so as to leave portions of the link between the ends straight as shown at9 but by reason of the twisting of the ends lying in intersecting planes as best seen in Fig. 1. w

It is desirable that the welds of alternate 1930. Serial No. 448,721.

links lie at opposite sides of the chain as this promotes the flatness of the chain when placed against the tread of the tire.

In practice the cross chain is placed with the rounded backs 8 against the tread of the tire so as to avoid wearing or abra-ding the tire and with the sharp edges projecting outchain becomes flexed as seen in Fig. 3 and as for example when brakes are applied the twisted end portions presentv different biting V edges It will be observed also that the saving that'member from rapid wear.

The forms of the parts can be changed without departing from the gist of the invention as claimed. 7

What I claim is: 1. A linkfor a tire chain having a twisted end and a sharp edge formed around one face thereof and its opposite face rounded.

2. A. link for a tire chain having its opposite ends twisted and asharp edge formed around one face thereof andits opposite face rounded.

- 3. A link of wire for a tire chain having its opposite ends twisted and a -sharp edge I formed longitudinally around one entire facethereof and its opposite face rounded, the

I wire of the link between said twisted ends being straight. V a FRANK E. STAHL.
